"Making the appointment online was super easy. A woman called the next day to confirm, which was nice. The locksmith who arrived (Nick) was highly professional and friendly. He did a great job at an affordable price. I am very happy with Mass Lock, I'd use them again and would recommend them to anyone."

Customers say: Quick response

"Roy was a lifesaver! On a Saturday night I realized my house keys went missing and I got an almost immediate response when I reached out. I made an appointment with him for the morning and he called 15 min prior to tell me he was on his way. When he arrived he was a few minutes early. He had my condo door unlocked in less than 5 minutes and I thought what he charged me, for a house call on Easter Sunday, was very fair. I really appreciated how responsive and reliable Roy was. I will definitely recommend him next time someone I know needs a locksmith."

"Awesome Service! I hired recently to install two garage door openers. I am pleased with his service. I described him as a professional, punctual and knowledgeable. He knows what he is doing. He visited prior to start the project and described what will be needed to complete the project and show up exactly on time (sharp) and completed the job very neatly and professionally. The best part and extra mile he gave in the whole project was follow up after the job is complete which mostly no one does after receiving the payment. Thank you so much for the job."

"We hired Bob on the strong recommendation of some friends who have used him for years, and he did a variety of handyman projects for us: snaked cable through a wall, hung mirrors, installed pegboards, repaired an exterior door, installed bathroom towel bars, etc. Bob performed all tasks very professionally in a reasonable amount of time, and we were very satisfied with the results."

Locksmiths FAQs, answered by experts

Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

Lubricating a door lock is an important part of door lock maintenance. It involves taking the lubricant of your choice (it’s best to use whatever the lock’s manufacturer suggests) and spraying it directly into the keyway. Push and pull your key in and out of the lock to make sure it’s all the way in. 

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.
